I had a set I used for my Oil change business. I found that if you put a rubber mat under the ramps, they wouldnt slide. After 3 years of 3 or 4 oil changes a day.. They did start to collapes, But I dont think you guys will ever use them as much as I did.


Now I used multiple lenths of 2x10s screwed together. As some of you have seen. I can put anything from a semi to a lowered vette on them.
